"Certainly it's the first time I've seen the father smile," Ms Adams said.

However, the dad appeared "exhausted" while the boy played on his phone and watched a movie during the six hour flight, she added.

The family has closely guarded the boy's identity throughout his ordeal.

He has worn a balaclava throughout all public appearances and the family home was on Monday shielded from public view by hessian bags strung up around it.

Reports that Channel Nine had signed an exclusive deal with the family to tell the boy's story resurfaced on Monday - something the channel vehemently denied.

"Nothing has changed, categorically there is no deal with his family. Full stop," Channel Nine spokesman David Hurley told AAP.

The boy was last week sentenced to two months in prison after being convicted on one count of drug use, but he was released on Sunday owing to time already served.

Before leaving Indonesia, he had to endure a two-hour stop at Kerobokan Prison before being taken to an immigration facility near the airport on Sunday.

The boy was spared the trauma of being held at Kerobokan after Indonesia's Justice and Human Rights Minister Amir Syamsuddin intervened and ruled it was not suitable.

Instead, he was allowed to remain at an immigration facility in Jimbaran, accompanied by his parents.

At Kerobokan Prison, which is "home" to a number of Australians, including Schapelle Corby and the Bali Nine - two of whom are on death row - the teenager was finger-printed, photographed and registered as a convicted drug user.

The family's lawyer, Mohammad Rifan, said the boy was delighted to finally return home.

"He's very happy to be going to meet his family and friends, even though he is still in a little shock after his time in Bali," Mr Rifan told reporters in Denpasar.

The federal government welcomed the teenager's arrival back in Australia and NSW Premier Barry O'Farrell said if asked, he would seek advice on providing support to the boy.

The boy's experience should act as a warning to other travellers, Mr O'Farrell added.
